[0038] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0039] Embodiment 1, please refer to Figures 1-6 The utility model provides a kind of technical solutions: a kind of for the concentrated sampling tube of gathering ethanol in fixed pollution source waste gas, including pipe body 1;Main module 103 is set to the top of pipe body 1, and the inside of main module 103 is provided with square groove 104;Two-way threaded screw 106 is movably connected in the inner wall of square groove 104 two sides, and the outer surface of two-way threaded screw 106 is screw-connected with two moving blocks 108;Clamping block 109 is fixedly connected on the one side of the outer surface of moving block 108;Limit post 107 is fixedly connected in the inner wall of square groove 104 two sides;Knob 105 is movably connected on the one side of the outer surface of main module 103;Check valve 110 is fixedly connected in the bottom center of main module 103, the inside of two moving blocks 108 is movably sleeved on the outer surface of limit post 107, the outer surface of pipe body 1 is fixedly connected with scale plate 101, the one side of the outer surface of knob 105 is fixedly connected on the one end of two-way threaded screw 106.

[0040] In this embodiment, ethanol is first captured directly from the exhaust gas of a fixed pollution source using a shock bottle or similar method. After capture, the operator inserts the hose of the shock bottle into the hole at the center of the main module 103, and then manually rotates the knob 105. The force generated by rotating the knob 105 drives the bidirectional threaded screw 106 to rotate forward. As the bidirectional threaded screw 106 continues to rotate forward, the two moving blocks 108 located on the outer surface of the bidirectional threaded screw 106 begin to move horizontally to both sides of the hose. When the two moving blocks 108 move horizontally, the clamping block 109 located on one side of the moving block 108 gradually and firmly clamps the hose as the moving block 108 moves. At the same time, the limiting post 107 engages the two moving blocks 108. The system includes a limit switch to prevent the two moving blocks 108 from spinning freely during movement. The ethanol is then transferred to the tube body 1. When the ethanol flows through the one-way valve 110 located at the bottom of the main module 103, backflow of ethanol can be effectively avoided. The square groove 104 provides good space for its internal components. The knob 105 facilitates subsequent manual operation. The operator can quickly determine the amount of ethanol collected directly from the surface of the tube body 1 through the scale plate 101. This prevents the hose from deviating from the sampling tube opening during the transfer of ethanol liquid, eliminating the need for repositioning, preventing liquid spillage, ensuring sampling quality, and preventing the traditional sampling tube from swinging significantly during manual operation. This system also prevents internal liquid backflow during transfer and improves the overall efficiency of ethanol collection.

[0041] Example 2, as Figures 1-6 As shown, a mounting plate 2 is fixedly connected to the top of the tube body 1 near the edge, and an inner plate 201 is threadedly connected to the inner wall of the mounting plate 2. The top of the inner plate 201 is fixedly connected to the bottom of the main module 103 near the center, and an elliptical block 102 is fixedly connected to the bottom of the tube body 1.

[0042] In this embodiment, in order to make the main module 103 reusable and quick to install and remove, the operator can attach the built-in plate 201 at the bottom of the main module 103 to the inner wall of the mounting plate 2, and then manually rotate the main module 103 to quickly install it on the top of the tube body 1. When quick removal is required, the main module 103 can be reversed, thereby improving the reusability of the main module 103 and improving the practicality of the sampling tube.

[0043] Working principle: in use, first through the impact bottle and other ways directly from the fixed source of pollution exhaust capture ethanol, capture is completed, the staff will impact bottle hose into the hole in the center of the main module 103, then manually rotate the knob 105, the force generated by rotating the knob 105 drive bidirectional screw rod 106 to positive rotation, with the continuous positive rotation of bidirectional screw rod 106, located on the outer surface of the two moving blocks 108 bidirectional screw rod 106 begins to move horizontally to the two sides of the hose, when the two moving blocks 108 move horizontally, the clamp block 109 located on the side of the moving block 108 gradually with the movement of the moving block 108 firmly clamped hose, while the limiting column 107 to the two moving blocks 108 limiting, prevent two moving blocks 108 in moving idling, then the ethanol transmission to the pipe body 1, when the ethanol flow through the one-way valve 110 located at the bottom of the main module 103, can effectively avoid the backflow of ethanol, square groove 104 for its internal components provides a good space, knob 105 is convenient for subsequent manual operation, the staff can through the scale board 101 directly from the surface of the pipe body 1 quickly judge the ethanol collection, so as to achieve in the transmission of ethanol liquid, avoid the hose deviates from the sampling pipe, no need to reposition, prevent liquid spill, protect the sampling quality, and the traditional sampling tube in manual operation, will swing greatly, prevent the internal liquid backflow when transmission, improve the ethanol overall collection efficiency, and in order to make the main module 103 can be reused, and quickly disassembled, the staff can paste the built-in plate 201 of the main module 103 bottom installation plate 2 inner wall, then manually rotate the main module 103 whole quickly install it on the top of the pipe body 1, when need to fast disassembly, reverse the main module 103, in this way improve the reusability of the main module 103, improve the practicability of the sampling tube.
